Changes in Phenotypic and Molecular Features of Naïve and Central Memory T Helper Cell Subsets following SARS-CoV-2 Vaccination.

Molecular changes in lymphocytes following SARS-CoV-2 vaccination are incompletely understood. We hypothesized that studying the molecular (transcriptomic, epigenetic, and T cell receptor (TCR) repertoire) changes in CD4 T cells following SARS-CoV-2 vaccination could inform protective mechanisms and refinement of future vaccines. We tested this hypothesis by reporting alterations in CD4 T cell subsets and molecular features of CD4 naïve and CD4 central memory (CM) subsets between the unvaccinated and vaccinated groups.

Dysglycaemia screening and its prognostic impact in patients with coronary artery disease: experiences from the EUROASPIRE IV and V cohort studies.

Background: Glucose perturbations can be detected by fasting plasma glucose (FPG), HbA, and the oral glucose tolerance test (OGTT). The highest yield is provided by OGTT. HbA is considered more practical.

Impact of the COVID-19 pandemic on psychotropic prescribing: a systematic review.

Objectives: The global prevalence of mental health disorders has risen significantly since the beginning of the COVID-19 pandemic. The pandemic has additionally caused disruption to mental health services, leading to a shift from in-person to remote service delivery. Given its long-term impact, it has become critical to evaluate whether changes in health delivery during the pandemic have had an effect on prescribing patterns for commonly prescribed psychotropic drugs.

Responding to Hitch in Fighting Mycobacterium Tuberculosis Through Arginine Multi Functionalized Mucoadhesive SNEDDS of Rifampicin.

The study aimed to develop thiolated pluronic-based self-emulsifying drug delivery system (SNEDDS) targeted delivery of Rifampicin coated by arginine for enhanced drug loading, mucoadhesion, muco penetration, site-specific delivery, stabilized delivery against intracellular mycobacterium tuberculosis (M. tb), decreased bacterial burden and production by intracellular targeting. Oleic oil, PEG 200 and Tween 80 are selected as oil, co-surfactant and surfactant based on solubilizing capacity and pseudo ternary diagram region.

Peptide-Coated Polycaprolactone-Benzalkonium Chloride Nanocapsules for Targeted Drug Delivery to the Pancreatic β-Cell.

Targeting current therapies to treat or prevent the loss of pancreatic islet β-cells in Type 1 Diabetes (T1D) may provide improved efficacy and reduce off-target effects. Current efforts to target the β-cell are limited by a lack of β-cell-specific targets and the inability to test multiple targeting moieties with the same delivery vehicle. Here, we fabricate a tailorable polycaprolactone nanocapsule (NC) in which multiple different targeting peptides can be interchangeably attached for β-cell-specific delivery.

The role of convalescent plasma and hyperimmune immunoglobulins in the COVID-19 pandemic, including implications for future preparedness.

Introduction: When Coronavirus Disease-19 (COVID-19) struck the world in December 2019, initiatives started to investigate the efficacy of convalescent plasma, a readily available source of passive antibodies, collected from recovered patients as a therapeutic option. This was based on historical observational data from previous virus outbreaks.

Methods: A scoping review was conducted on the efficacy and safety of convalescent plasma and hyperimmune immunoglobulins for COVID-19 treatment.

Blood pressure, brain lesions and cognitive decline in patients with atrial fibrillation.

Background: The influence of atrial fibrillation (AF) and blood pressure (BP) on brain lesions and cognitive function is unclear. We aimed to investigate the association of BP with different types of brain lesions and cognitive decline in patients with AF.

Methods: Overall, 1,213 AF patients underwent standardized brain magnetic resonance imaging at baseline and after 2 years, as well as yearly neurocognitive testing.

Posthospitalization COVID-19 cognitive deficits at 1 year are global and associated with elevated brain injury markers and gray matter volume reduction.

The spectrum, pathophysiology and recovery trajectory of persistent post-COVID-19 cognitive deficits are unknown, limiting our ability to develop prevention and treatment strategies. We report the 1-year cognitive, serum biomarker and neuroimaging findings from a prospective, national study of cognition in 351 COVID-19 patients who required hospitalization, compared with 2,927 normative matched controls. Cognitive deficits were global, associated with elevated brain injury markers and reduced anterior cingulate cortex volume 1 year after COVID-19.

Long-term antibiotic prophylaxis for prevention of rheumatic fever recurrence and progression to rheumatic heart disease.

Background: Rheumatic fever is a non-suppurative, inflammatory sequela of group A Streptococcus pharyngitis that can occur at two to four weeks after infection. Following an episode of rheumatic fever, there is a risk of developing rheumatic heart disease (RHD) later in life that carries significant risk of morbidity and mortality. RHD remains the largest global cause of cardiovascular disease in the young (age < 25 years).

Increased Sensitivity to Effort and Perception of Effort in People with Schizophrenia.

Objective: Motivational deficits in schizophrenia are proposed to be attributable in part to abnormal effort-cost computations, calculations weighing the costs vs. the benefits of actions. Several reports have shown that people with schizophrenia display a reduced willingness to exert effort for monetary rewards when compared to controls.

Red Blood Cell Transfusion in European Neonatal Intensive Care Units, 2022 to 2023.

Importance: Red blood cell (RBC) transfusions are frequently administered to preterm infants born before 32 weeks of gestation in the neonatal intensive care unit (NICU). Two randomized clinical trials (Effects of Transfusion Thresholds on Neurocognitive Outcomes of Extremely Low-Birth-Weight Infants [ETTNO] and Transfusion of Prematures [TOP]) found that liberal RBC transfusion thresholds are nonsuperior to restrictive thresholds, but the extent to which these results have been integrated into clinical practice since publication in 2020 is unknown.

Objective: To describe neonatal RBC transfusion practice in Europe.
